ARC is a seasonal self-improvement app built to help you reset your life, stay disciplined, and improve your life the way nature designed it: in focused seasons. Instead of endless to-do lists, ARC gives you a clear structure: 90-day seasonal Arcs. Winter. Spring. Summer. Autumn. Each Arc is a focused chapter of your life. Choose habits and goals that fit the energy of the current season, build your routine, track your consistency, and watch your progress compound day by day. BUILD YOUR ARC Create a personal 90-day transformation plan around the habits and goals that matter most to you. Fitness, focus, sleep, learning, work, discipline, mindset, routines, personal growth — your Arc is yours to define. SEASONAL HABITS AND GOALS ARC helps you improve your life in rhythm with the seasons. Each season can guide a different focus: Winter for discipline and deep work. Spring for growth and new habits. Summer for energy, health, and action. Autumn for reflection, consistency, and refinement. TRACK DAILY HABITS Log your habits every day and build momentum through simple, focused tracking. ARC helps you see what you completed, what you missed, and where you need to improve. STAY CONSISTENT Your streaks, completion rate, and consistency history help you understand your real discipline over time. No noise. No complicated setup. Just a clear view of your progress. SEASONAL RESET SYSTEM Every season is a new chapter. ARC is designed around four powerful cycles: • Winter Arc • Spring Arc • Summer Arc • Autumn Arc Use each season to reset, refocus, and become better than the version of yourself from the last Arc. GOALS, HABITS, AND PROGRESS ARC helps you connect your daily actions to bigger goals. Track what you are building, measure your effort, and keep your long-term transformation visible. DISCIPLINE INDEX See your progress through simple stats and visual feedback designed to keep you aware of your consistency and performance. MINIMAL, FOCUSED DESIGN ARC is built for people who want a serious, clean, distraction-free habit tracker. No clutter. No childish gamification. Just a sharp system for personal growth. PRIVATE BY DESIGN Your personal ARC data is stored on your device and/or in your iCloud, depending on your settings. We do not collect your personal habit, goal, streak, note, or progress data on company servers. ARC CAN HELP YOU: • Build better habits • Track daily discipline • Stay focused on long-term goals • Create a 90-day self-improvement plan • Reset your routine each season • Improve consistency • Track streaks and progress • Choose habits that fit the current season • Stay accountable to yourself • Turn self-improvement into a clear system WHO ARC IS FOR ARC is for people who are tired of vague motivation and want structure. For students. For founders. For athletes. For creators. For anyone trying to become more disciplined, focused, and consistent. This is not just a habit tracker. This is your seasonal reset system.

Your Winter Arc, tracked. The Winter Arc is simple: while everyone else coasts through the cold months, you lock in. Pick your window (Oct 1 to Dec 31 is the classic), write the daily rules you refuse to skip, sign your name, and show up every single day. WRITE YOUR NON-NEGOTIABLES Up to 10 daily rules: train every day, 10k steps, no alcohol, read 10 pages, up before 6, no phone after 9pm. Yours, in your words. Tap a suggestion or type your own. SIGN THE CONTRACT A contract card with your rules, your dates and your signature. Post it before day one. Telling people is half the discipline. CHECK IN. LOCK THE DAY. Every day, check off each rule. All of them done = a perfect day and a streak. Miss one and the grid shows it. No hiding. WATCH THE ARC FILL UP A 92-day grid (or however long you set), perfect-day streak, best streak, rules hit rate, days left. Share the progress card whenever you want. BUILT FOR THE LONG HAUL - Optional daily reminder at the hour you choose - Works fully offline. No account, no sign-up, nothing leaves your phone - Any dates: Oct 1 to Dec 31, 90 days from today, Nov 1 to Jan 31, or your own - Available in English, German, Spanish, Portuguese, French and Italian Free to use, supported by a small ad on the progress screen. Your check-in list stays ad-free, always. Winterlock is a habit tracker, not a coach or a medical tool. The only thing it measures is whether you kept your word.
